Verified step by step guidance1
Understand the process of meiosis, which consists of two consecutive divisions: Meiosis I and Meiosis II.
Recall that during Meiosis I, homologous chromosomes are separated, not sister chromatids. This is a key distinction from mitosis.
Identify that in Anaphase I, homologous chromosomes are pulled apart to opposite poles, while sister chromatids remain together.
Recognize that Meiosis II is similar to mitosis, where the separation of sister chromatids occurs.
Conclude that during Anaphase II of Meiosis II, sister chromatids are finally separated and pulled to opposite poles of the cell.
